Sentry Key Immobilizer System (Skis)

All modules of the Ignition Node Module (IGNM) have transponder chips in all keys and FOBIK. Upon failure of proper SKIS communication to the Remote Frequency Hub (RFH) Module, the vehicle will not be allowed to crank. The engine will not allow another crank event to occur on the key cycle that the failure occurred. A full key down sequence must be performed for the engine to crank again. Refer to OPERATION .
